SermonSpeaker creating lots of huge zip files

I guess this could help with memory usage, but other than that I don't see any advantages. Or do I miss something?

I'm more tempted to add a new toggle to the series where you can disable the download function for big series (like a "general stuff" series). Or a parameter which only allows downloads for series with less than the set amount of sermons. I think the series download is useful for small series where people want to listen the whole series. It doesn't make a lot of sense if it's a huge series where people probably are only interested in a few sermons.

What i was thinking those huge series can be broken out into groups of 10. sorted by date. older ones will never be recreated since you probably never change them. only last set of 10 will be recreated.

That would be even more complicated
What if a sermon in a series changes the date? Or a new sermon is inserted into a series? I would have to recreate all of them anyway. SermonSpeaker would have to calculate which files have to be changed and which not, and there is no tracking of the changes that would help with that.

I think if the bug is fixed, then the on-demand with progress bar sounds like the best solution all things considered.

Do I understand it correctly that when a user hits Download Series the zip files is only recreated if it has changed? Or does it always create the zip file again?

I always have to recreate it since I have no clue if something has changed in the series.

I understand.

In that case there should definitely be an option to deactivate series downloads for large series. E.g. I have Heidelberg Catechism series which has almost 100 sermons!
